The Ultimate Guide to Orange 20 Rt
No modelling menus, no presets — just a straightforward, characterful practice amp. Here's what the Orange Crush 20RT actually offers.
If you've come across the name "Orange 20 RT" while amp-hunting, you're looking at the Orange Crush 20RT — a small, 20-watt practice combo from one of British amp-building's most recognisable names. It's not trying to be clever or complicated, and that's genuinely the whole appeal. Here's what it actually offers.
What it is, in plain terms
The Crush 20RT is a solid-state guitar combo built around two channels — clean and dirty — Orange's own high-gain preamp, a shared three-band EQ, digital spring reverb, a built-in chromatic tuner, an auxiliary input for backing tracks, and a headphone output with cabinet simulation (CabSim) for silent practice. The "RT" in the name simply stands for reverb and tuner, distinguishing it from the plainer Crush 20.
It's worth being clear about one thing: this isn't a modelling amplifier. There's no menu of amp emulations or a library of built-in effects. The signal path is analogue throughout — the reverb and headphone CabSim are the only digital elements — which is exactly why reviewers keep describing it as an uncomplicated, no-frills practice amp.

The two channels, explained
The clean channel gives you a relatively open, pedal-friendly platform — a sensible base if you're building a pedalboard around it. The dirty channel is where the Orange character really lives: a proper high-gain preamp voiced for the classic Orange overdrive and distortion sound, without needing a single pedal. Because the EQ is shared between both channels, adjusting bass, middle or treble affects whichever channel you're on — a simplification that keeps things easy to use, at the cost of setting radically different tone profiles for clean versus dirty.
Reverb, tuner and the headphone output
The onboard digital spring reverb adds ambience straight from the front panel, no separate pedal required. The chromatic tuner is a genuinely handy inclusion for a practice amp — mute the signal, tune up, and get playing. The headphone output is arguably the standout practical feature: it's loaded with cabinet simulation, so headphone practice sounds meaningfully more like a real speaker than a raw, untreated signal would. It's ideal for late-night playing, though it's worth knowing there's no USB audio here — this isn't a recording interface, just a considerate way to practice quietly.
What it's genuinely good at — and where it falls short
This amp suits bedroom and apartment practice, beginner and intermediate setups, players who want an easy high-gain sound without pedals, and anyone who wants to practise along with backing tracks through the aux input. Where it falls short: the single 8-inch speaker won't move air like a 10- or 12-inch driver, there's no effects loop (so delay and reverb pedals sit before the preamp rather than after), and it isn't built with gigging or full-band rehearsal volume in mind.
Using pedals with it
The clean channel is a genuinely practical platform for overdrive, distortion, modulation and delay pedals. You can stack pedals into the dirty channel too, but adding extra gain stages on top of an already high-gain preamp can get compressed and congested quickly, so use a lighter touch there. One real limitation worth knowing: there's no effects loop, so time-based effects like delay and reverb sit before the preamp rather than after it — less flexible than a loop-equipped amp, though rarely a dealbreaker at bedroom volume.

The bottom line
The Orange Crush 20RT isn't trying to be a do-everything modelling platform, and that restraint is precisely its strength. If you want a small, honest amp rather than a menu of presets, the Orange Crush 20RT still makes a strong case for itself. For straightforward practice, a strong built-in overdrive sound and genuinely useful extras like the tuner and CabSim headphone output, it remains a sensible, characterful little amp.
